JOHN W. ROSENBATIM, OF SAYRE, OKLAHOMA.

WELL DRILL.

Application filed October 19, 1922. Serial No. 595,589.

To @ZZ yw/wm t may concern.'

Be it known that I, JOHN W. RosENBAUM, citizen of the United States, residing at Sayre, in the county of Beckham and State 6 of Oklahoma, have invented certain new and useful Improvements in Well Drills, of which the following is a specification.

The present invention relates to a well drill and has for its principal object the provision of a simple and efficient operating mechanism which may be manufactured at a comparatively small cost yet be durable and well adapted to the purpose for which it is designed.

The mechanism is designed to be used in conjunction with a well drill for lifting and releasing the same.

With the above and numerous other objects in view as will appear during the description, the invention resides in certain novel features of construction and the combination and arrangement of parts as willy be hereinafter claimed.

In the drawings Figure 1 is a side elevation of the drilling machine embodying my invention,

Figure 2 is a top plan thereof, and

Figure 3 is a `detailed section taken therethrough.

Referring to the drawings in detail it will be seen that the machine vincludes a horizontally disposed frame 1 and a vertically disposed frame 2 which supports the former intermediate its ends, and suitable bracing bars 3 are extended from the top of the vertically disposed frame 2 and attached to the horizontally disposed frame 1 intermediate its ends. A shaft 4 is journalled in the frame 1 adjacent the ends attached to the vertically disposed frame 2, and supports the drum 5 having a flexible cable 6 lwound thereabout and extending over a pulley 7 mounted in the upper end of the frame 2. This cable continues downwardly as disclosed in Figure 1 and supports an earth drilling tool 8.

A jerk cable 9 is suitably attached at one end to a pulley-10 engaged with the cable 6 and is attached at its other end to a shaft 11. This shaft 11 is rotated in any suitable more fully described and manner by operation of the clutch segment 12 controlled by the lever 13. A wheel 14 is mounted on the shaft 11 and includes a clutch segment 15 .which is engageable by the clutch segment 12 for rotation of this wheel. This wheel 14 includes a cam element or panel' 16 engageable with the jerk cable line for lifting the earth drilling tool 8. When the jerk cable slips ofi" of the cam element or panel 16 the tool is allowed to drop. This motion is continued and the cable 6 may be lengthened as required.

A bar 17 is disposed between vertically disposed frame 2 and the bracing bars 3. A spring 18 is attached to the intermediate portion of this bar 17 and its lower end is attached tothe pulley 10. When the parts are in position shown in Figure l this spring 18 will be under tension tending to retain the jerk rope 9 taut.

Although I have described my invention with some degree of particularity, it is to be understood that the present embodimentl has been disclosed merely for an example and that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit of the invention as hereinafter claimed.

Having thus described my what I claim as new is l. In a machine of the class described, a frame, an earth drilling tool associated with the frame, a cable disposed over the frame for supporting the tool, a second cable engaged with the first cable, a spring on the frame supporting the end of the second cable attached to the first cable, and means for jerking the second cable.

In a machine of the class described, a frame, an earth drilling tool associated with the frame, a cable disposed over the frame for supporting the tool, a second cable, a pulley on one end of the second cable engaged with the first cable, a spring on the frame supporting said pulley, and means for jerking the second cable. j

3. In a machine of the class described, a frame, an earth drilling tool associated with the frame, a cable disposed over the frame invention,

for supporting the tool, a second cable, al

pulley on one end of the second cable enin the manner and-for the purpose specified. gaged With the rst cable, a spring 0n the In testimony Whereofl ax my signature frame supporting said pulley, a Wheel in presence of two Witnesses.

mounted on Said frame, a cam on said Wheel, JOHN W. ROSENBAUM. 5 means for supporting the other end of the lVtnesses:

second cable whereby the cam may engage W. BEN TURNER,

the second cable for jerking the Same all O. B. THOMER.
